Yes, I know.. Unfortunately TRSearch doesn't work and Tomb Share is canceled..
And then, there are a lot of remakes of outfits from outfits that weren't release, and I don't know if they want that I'll release mine. I wanted to ask them, but I can't find them anywhere..
They don't know about my remakes..

It's indeed easy, if you have a Gmail account, then you also have your 15GB space on Google Drive
You simply upload your packages, then press right click on a file you uploaded, and at the end click on "get shareable link"
Also, just the people who has the link can download it

There's this thing called Tutorials and Resources here on this very forum.
And in this section is this thread called TRLE/TRNG Resources.

If you want to release some outfits, you can send me a link to the downloads and I can upload it here onto our server in case you rather not use something like Google Drive but another hosting site instead.
By uploading content on our server we can make sure links don't go dead after some time, like it is happening a lot in the XNALara section.

As for getting permission from the builders who originally created an outfit: lots of builders are also active over at trle.net forums. You might be able to get in contact with at least some over there, if you haven';t tried that already.
I'm thinking for example of EssGee for the Padme outfit, and Trix for her outfit.
